One day later, 49ers head coach Jim Harbaugh is still giddy. Chatty, even.

Harbaugh spent most of his weekly news conference today re-living and savoring Sunday’s 23-20 playoff victory over Green Bay. There was a lot to savor, from Colin Kaepernick’s big game to the defense mostly containing Packers quarterback Aaron Rodgers.

And, of course, Harbaugh relished the fact that his team conquered the frigid elements at Lambeau Field. That brought out the machismo in San Francisco’s head coach.

“Personally, I’m ecstatic for the players,” he said. “I haven’t found anything that makes you feel like a man more than beating your opponent in a playoff game, beating the crowd, beating the elements.”

Harbaugh made a point of noting Kaepernick’s ability to thrive in the nasty elements. He ran seven times for 98 yards and completed 16 of 30 passes for 227 yards and a touchdown.

Beyond the numbers was the way Kaepernick carved up the Packers — scampering downfield on the frozen tundra and unleashing throws oblivious to the cold weather and whipping winds.

“We’ve got a good bad-weather quarterback,” Harbaugh said. “The thing I didn’t envision when we drafted Colin was how unbelievably effective he would be on a bad field. He was running like a gazelle, like he was the only one on the field. …

“He’s able to throw a ball that pierces the elements. He’s showed that in the rain, too — he can pierce a defense with velocity on his throws and the tightness of his spirals.”

Harbaugh watched video of the game on the team’s charter flight home Sunday night — “that’s as happy as I can possibly be,” he said — and then started to turn his attention to the Carolina Panthers, whom the 49ers will meet this coming Sunday in Charlotte, N.C. The Panthers smothered the 49ers, 10-9, at Candlestick Park on Nov. 10 and offer a much stronger defense than what the 49ers faced in Green Bay.

San Francisco’s success the past three seasons could cause some disruption in the coaching staff. Harbaugh acknowledged today that some teams have called the 49ers to speak to their assistant coaches about head coaching vacancies.

Offensive coordinator Greg Roman is reportedly among the candidates for open jobs in Washington and Minnesota. Harbaugh wouldn’t say which teams called about which coaches, but he mentioned Roman, defensive coordinator Vic Fangio, defensive line coach Jim Tomsula and special teams coach Brad Seely as potential candidates.

“I would imagine there will be some interviews in the coming weeks,” Harbaugh said. “Those are some great coaches. I don’t think anybody has a better staff than we have here. … It will be a surprise if somebody doesn’t become a head coach.”
